The page now tells the one history of the Church in two ordered movements: first the Old Testament preparation of Christ, then the New Testament Church that is publicly manifested at Pentecost and continues visibly up to now.

Each part has its own introduction, tree, maps and study panels. Hover a node for a short note; click it for persons, places, themes, biblical witnesses, historical witnesses and links.

Tree IFrom Adam to ChristPromise, Israel, covenant and preparation among the nations. Tree IIFrom Pentecost up to nowThe Catholic Church is public from Pentecost and continues through councils, papal continuity, missions and visible communion.

Part I · Old Testament

Promise, preparation and the line toward Christ

The history of the Church is not a modern institutional story that begins late in time. It is rooted in the divine economy from creation onward. God prepares a people, a covenant, a priestly worship, a royal line and a prophetic expectation so that the Incarnation is not an isolated event but the fulfilment of a long visible preparation.

Tree I therefore reads the Old Testament as sacred history ordered to Christ: Adam and Eve, Noah, Abraham, Israel, the Exodus, the tabernacle, David, the prophets, exile, return and the final expectation of the Messiah.

Tree ISalvation HistoryFrom Adam to Christ

The line of promise begins with creation, passes through the patriarchs, Israel, law, kingship, exile and return, and reaches fulfilment in the Incarnation, Cross and Resurrection of Christ.

Tree I maps

Tree I Map Slider — Promise, Israel and the Holy Land

These maps belong directly under Tree I: Salvation History. The active panel now carries a longer description and the principal biblical witnesses for the selected map.

**The World before the Flood***Biblical witnesses: Genesis 2:8–14; Genesis 4; Genesis 5; Genesis 6–7*This orientation map gathers Eden, the rivers, Cain, Seth, Enoch and Noah into one traditional antediluvian frame. It helps the reader situate creation, the first generations, the spread of sin and the approach of the flood.

Parallel biblical scenes

Tree I Parallel Slider — Old Testament Scenes, Sanctuaries and Genealogies

These supplementary images deepen the Old Testament branch with visual scenes of the flood, Babel, tabernacle, ark, temple, Jerusalem and genealogical continuity. Each active panel includes a fuller description and the main biblical references.

**Noah’s Ark and the Flood***Biblical witnesses: Genesis 6–9*A dramatic visualisation of the flood places judgment, preservation and covenant renewal before the reader. It can accompany the biblical account of Noah, the ark and the survival of living creatures by God’s command.

Part II · New Testament and Church History

From Christ and Pentecost up to now

The Old Testament line reaches its centre in Jesus Christ. From his Incarnation, Cross and Resurrection the Church is not merely expected but visibly given. At Pentecost the Catholic Church is publicly manifested in apostolic preaching, baptism, Eucharist, hierarchy, mission and communion.

Tree II therefore does not show a movement from Pentecost to a later Catholic Church. It shows the Catholic Church from Pentecost up to now: apostolic witness, councils, Roman succession, missions, saints, reforms, doctrinal definitions and the continuing visible communion of the Church.

Papal line

Continuous Roman Succession

From Peter to the present Roman pontiff, the papal line is presented as a visible historical succession. The portrait strip uses the imported image archive instead of generated placeholders.

Pontifex Romanus

1 · Peter

Reign: c. 30-64/67

Apostle and martyr in Rome; the visible root of the Roman succession.

Biographical summary

Peter is listed here as Roman pontiff number 1, in the visible succession from Saint Peter.

The catalogue gives his pontificate as c. 30-64/67.

He belongs to the apostolic or immediately post-apostolic age, when the Roman Church was still emerging from persecution and living memory.

Apostle of Christ and martyr in Rome, Peter is the visible root of the Roman succession.

The New Testament shows him confessing Christ, preaching at Pentecost and strengthening the brethren.

Catholic history reads the Roman line through the martyrdom and witness of Peter.

The entry should be read historically: papal biographies vary in source depth, especially for the earliest centuries.

The Catholic importance of the line is not that every pope is equally prominent, but that the Roman see remains a visible point of continuity.

This local summary is written as full page text, so the detail panel does not depend on an external biography link or pop-up.

Concilia

Concilia Oecumenica

All 21 ecumenical councils are shown here together with the Apostolic Council of Jerusalem, because Catholic continuity presents conciliar judgement as biblically grounded from the beginning.

Date	Council	Pope / Roman context	Place	Principal question	Doctrinal or disciplinary act	Continuity note
c. 49	Apostolic Council of Jerusalem	Peter, James and the apostles	Jerusalem	Gentiles, circumcision and the law	Provides the biblical foundation for councils: debate, appeal to Scripture, apostolic judgement and public decree.	Acts 15 establishes that the Church answers doctrinal crises publicly and authoritatively.
325	Nicaea I	Sylvester I	Nicaea	Arianism; consubstantiality of the Son	Confesses the Son as consubstantial with the Father and produces the Nicene core of the creed.	Safeguards the Church's worship of Christ as true God.
381	Constantinople I	Damasus I	Constantinople	Divinity of the Holy Spirit; Nicene faith	Confirms and expands the Nicene creed, especially on the Holy Spirit.	Consolidates the Trinitarian confession used by the whole Church.
431	Ephesus	Celestine I	Ephesus	Nestorianism; Theotokos	Defends the unity of Christ's person and confesses Mary as Theotokos.	Shows Marian doctrine serving Christological truth.
451	Chalcedon	Leo I	Chalcedon	Two natures of Christ	Receives Leo's Tome and teaches one person in two natures without confusion or division.	One of the decisive Christological anchors of Catholic doctrine.
553	Constantinople II	Vigilius	Constantinople	Three Chapters controversy	Clarifies Chalcedonian Christology against divisive interpretations.	Demonstrates that councils often clarify earlier councils rather than replace them.
680-681	Constantinople III	Agatho; confirmed by Leo II	Constantinople	Monothelitism	Defines two wills and two operations in Christ according to his two natures.	Protects the fullness of Christ's humanity and therefore the reality of redemption.
787	Nicaea II	Hadrian I	Nicaea	Iconoclasm	Defends the veneration of holy images while distinguishing it from adoration due to God alone.	Grounds sacred images in the Incarnation.
869-870	Constantinople IV	Hadrian II	Constantinople	Photian crisis and ecclesial order	Addresses the deposition and restoration disputes around the see of Constantinople.	Shows intensifying East-West tensions before the later hard rupture.
1123	Lateran I	Callixtus II	Rome	Investiture settlement	Confirms the settlement after the Investiture Controversy and strengthens clerical discipline.	First ecumenical council held in the West.
1139	Lateran II	Innocent II	Rome	Schism and reform	Repairs schismatic disorder and continues reform of ecclesiastical life.	Reinforces the Gregorian reform trajectory.
1179	Lateran III	Alexander III	Rome	Papal election and discipline	Sets the two-thirds papal election rule and treats reform and heresy.	Strengthens juridical stability in papal succession.
1215	Lateran IV	Innocent III	Rome	Eucharist, confession and reform	Uses the language of transubstantiation and legislates annual confession and communion.	One of the most consequential medieval syntheses of doctrine and discipline.
1245	Lyon I	Innocent IV	Lyon	Imperial conflict and reform	Addresses the crisis around Frederick II and broader ecclesial reform.	Illustrates the collision of papal and imperial orders.
1274	Lyon II	Gregory X	Lyon	Union, reform and conclave	Attempts reunion with the Greeks and treats papal election and reform.	Visible unity remains a major conciliar aim.
1311-1312	Vienne	Clement V	Vienne	Templars, reform and doctrine	Suppresses the Templars and deals with reform and doctrinal questions.	A council of institutional crisis and re-ordering.
1414-1418	Constance	Martin V	Constance	Western Schism	Ends the Western Schism and condemns major errors while treating reform.	Restores a recognised Roman pontiff after a severe governance crisis.
1431-1445	Basel-Ferrara-Florence-Rome	Eugene IV	Basel / Ferrara / Florence / Rome	Union with eastern churches	Issues union decrees and doctrinal texts on procession, sacraments, purgatory and hierarchy.	Politically fragile, but doctrinally significant.
1512-1517	Lateran V	Julius II; Leo X	Rome	Pre-Reformation reform	Addresses reform, preaching and governance shortly before the Protestant rupture.	Shows that reform concerns existed before 1517.
1545-1563	Trent	Paul III; Julius III; Pius IV	Trent	Reformation crisis	Defines Catholic doctrine on Scripture and Tradition, original sin, justification, the sacraments, the Mass and orders, while reforming discipline.	The great council of Catholic reform and doctrinal clarification.

1962-1965	Vatican II	John XXIII; Paul VI	Rome	Church, revelation, liturgy and mission	Teaches on revelation, the Church, liturgy, bishops, ecumenism, religious liberty, mission and the modern world.	Its reception must be read within the one continuous Catholic tradition.

Heresies

Gnosticism, Arianism, Nestorianism, Monophysitism, Iconoclasm, Jansenism and Modernism show recurring attempts to reduce creation, Christ, grace, worship or dogma.

Open historical heresies

Schisms and ruptures

Novatianism, Donatism, the East-West break, the Western Schism and the Protestant ruptures show how visible unity can be wounded without erasing the central Catholic line.

Open apologetics

Mission and reform

The same Church that defines doctrine also evangelises peoples, reforms discipline, codifies law, teaches catechisms and sends the Gospel into every continent.
